To all whom it may concern.-

-Be it known that I, CHARLES SHANNON, a

resident of Dayton, in the county of Montgomery and State of Ohio, haveinvented a new and useful Improvement in Paint Dis- My invention relatesto a device for ad vertising, displaying,

demonstrating, and testingpamts, o1ls, varnishes, or other coatingliquids or semiliquids, in a practical,

purchasing agents, dealers, handlers, or consumers of such materials.

Paints, oils, varnishes, and materials'for kindred uses must-possesscertain working, wearing, and keeping qualities in order to effectivelyserve their purpose and meet the requisites of the trade. The mostessential properties are, first, consistency, color, thickness of themixture, and thoroughness of intermingling of the solids and liquids,(pigments, gums, oils, thinners, &c.,) so as to keep in workablecondition for indefinite periods without separating, curdling,precipitating or hardening in storage receptacles or holders; second,the working properties most essential are smoothness of spreading orflowing under the brush, completeness of covering the surface, luster,uniformity and thickness of the layers or coats, and the setting anddrying of the coats free from pits, streaks, or sags third, itsdurability or wearing property depends upon the elasticity, adhesion ofthe thin layers, films, or coatings, also their resistance toatmospheric and gaseous influences, together with their proper-r tiesfor repelling moisture or liquids. In order that architects, engineers,purchasingagents, dealers, handlers, or consumers of such materials maydetermine that the products offered them are possessed of all theseproperties, it is desirable that they have and speedy 3 which alsopreferably will be of glass, isinsome convenient, compact, method oftesting the same.

My invention has for its object to furnish a device whereby theseseveral properties can be determined, tested, or demonstrated.

To this end the invention consists, generally stated, in a suitablesupport, preferably a glass'receptacle, having supported verticallytherein a smooth plate, preferably of glass, isinglass, or othertransparent material, on which the materials can be spread and remain ina vertical position until dry, so that any tendency of the wet coatingto drop, run, streak, or sag is readily shown, as well as theuniformity, thickness of layer, color, and drying properties of suchcoating are readily demonstrated. This receptacle also contains thereinone or more tubes, preferably of glass, for containing a sample orsamples of the product, wherein its consistency or homogenity and-anytendency to evaporate, separate, precipitate, or harden may be observedfrom time to time. This receptacle also contains therein one or moreupright tubes, preferably of glass, in the mouth of which is held asmall funnel, in which rests a coating-film folded in filtering form,which is filled with water or an alkali or acid liquid to determine thewater-repellant properties of said film or coating.

The device also contains means for testing the moisture or liquidrepellant properties of the coating material.

In the accompanying drawings, Figure 1 is a perspective view of mydevice. Fig. 2 is an enlarged detail view illustrating one manner oftesting the water or moisture repellant qualities of the material. Fig.3 is a detail sectional view of the glass plate upon which the paint orother material is coated, and Fig. 4 is a detail view of one of theclamps used.

My device has been designed with a view of being left upon the table ordesk of users or prospective purchasers of paints, oils, varnishes, orthe like, and I have therefore kept in view the neatness orattractiveness of the device, as well as having the parts so arrangedand constructed that all tests are readily visible at all times.

My device contemplates a suitable support for the different testingdevices, and for neatness and visibility of all tests this preferably ismade in the form of a glass receptacle 1, which is shown in the form ofa straight-sided tumbler or cup. In this receptacle is supported invertical position a smooth plate 2-,

glass, or other transparent material, for reasons hereinafter referredto. a coating of the paint, oil, varnish, or other material to be testedwill be spread in order to test the smoothness of spreading of thematerial. This plate is very smooth and held in a vertical position, sothat if the ma- Upon this plate terial has any tendency to run, streak,or sag this test will bring out any such defect. The coating of materialon the plate is readily visible through'the receptacle, so that it canbe readily seen whether the material dries smoothly and uniformly.

In order to test the water and moisture repellant qualities of the paintor other material, two tests can be made. I One consists in providingthe plate 2 on one surface with a slight depression 3, in which can beplaced a suitable material 4 of such a nature that its condition, color,or other characteristic changes under the application of water ormoisture. Various anilin powders may be used for this purpose, or simplypulverized lead from an indelible pencil. A variety of other agents willanswer the purpose. This agent is placed in the concave depression 3,and then a coating of the paint or other material 5 is spread over thesame. If this coating is impervious to water no moisture will reach thechemical agent 4, and consequently its color or condition will remainunchanged. It is for this reason that the .plate 2 is preferably ofglass or other transparent material, so that the condition of this agentcan be readily observed. Should, however, the coating of paint not beimpervious to moisture, this agent will change color. This action can bereadily observed, and therefore the moisture-repelling quality of thematerial accurately tested.

In case a more severe test of the water-repellant qualities or of acidor alkaline repelant qualities is to be made a coating of the paint willbe spread upon some smooth surface and after it dries or sets will becarefully removed and placed in the form of an ordinary filter-paper 6in an ordinary filterin funnel 7, which will be placed in a suitabletube, such as an ordinary glass testtube 8, supported in the receptacle1, which test-tube at its bottom contains a quantity of chemical agent 9of the character above referred to. The funnel above thefilm 6 will befilled with water or an acid or alkaline liquid, and in order to holdthe funnel against undue movement the stem 10 of the funnel will beprovided with a spacing-gland 11, which may be a disk of rubber or thelike. If the film 6 is not entirely water or liquid proof, the chemicalagent in the bottom of the test-tube will soon be affected.

In order to test the non-precipitating or non-caking qualities of thematerial, I provide one or more other tubes 12, which will be filledwith a sample of the material or materials and allowed to stand. Fromday to day these tubes can be tested by plunging down into them abroom-straw or the like.

and if the material has a tendency to precipitate or cake at the bottomthis test will bring out such fact. A plurality of such tubes preferablywill be employed, so that comparisons between several similar materialsmay be made.

The device as a whole is very compact and I neat of appearance, so thatit can be set upon the desk or table of -a user or purchaser and all ofthe tests can be observed from day to day and progress of changes noted.This simple device contains the means for testing the smoothness ofspreading of the material, its tendency to streak, run, or sag on smoothvertical surfaces, also the water or moisture repellant qualities of thematerial, and also the tendency of the material to precipitate or cakeat the bottom or a storage-receptacle, the latter being a good test ofwhether the solid parts of the material are well held in suspension inthe liquid thereof.

I do not limit myself to the exact form and arrangement of parts shown.

The various test-tubes may, if desired, be hung on the outside of thecup; but it is preferred to have all the parts on the inside, as theywill therefore be less liable to injury or disturbance.

What I claim is 1. A device for testing paintand the like, comprising asuitable support, and a transparent plate held thereby in a verticalposition and provided with a depression on one face to receive achemical agent and adaptedv to have the material to be tested spread onits face and over the chemical agent in said depression.

2. A device for testing paint and the like, comprising a transparentreceptacle, and a transparent smooth-faced plate removably supportedtherein in a vertical position and provided with a depression in itsface to receive a chemical agent and adapted to have the material to betested spread on its smooth face and over the chemical agent.

In testimony whereof I, the said CHARLES SHANNON, have hereunto set myhand.

CHARLES SHANNON.
